Oil-finish for photographs



UNITED STATES PATE T OFFICE.

ADOLPH C. BRENDECKE, OF CHICAGO, ILLINOIS.

OIL-FINISH FOR PHOTOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 429,558, dated June 3,1890.

Application filed October 3, 1889.

To all whom it may concern:

Be it known that I, ADOLPH O. BRENDECKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Composition of Matter for Producing OilPictures by Means of an Atomizer, of which the following is aspecification.

, Atomizers or air-brushes, used by artists for shading purposes, arewell known and do not require any description. The same have beenemployed for finishing photographs and other pictures, producingbeautiful effects; but they seem to have proved to be a failure whenapplied for producing oil-paintings. Heretofore oil of turpentine, oilof lavender, or benzine have been taken for dissolving oil-colors to beused for painting, and for this very reason the use of an atomizer orair-brush for producing oil-paintings has not been a success, as theoil-colors so prepared are not capable of being delivered or thrownrapidly upon the picture or drawing to be painted in the form of a finespray by means of said atomizers, or in case they are do not drypromptly, so as to prevent flowing or running. To overcome thisdifficulty is the object of my invention; and the same consists inadding to the oil-colors or oil-paint to be used, first a small quantityof oil of turpentine, and thereupon about the same quantity of sulphuricether, as the oil-color itself has been.

Serial No. 325,890- (No specimens.)

It is evident that as all substances which are more volatile than oil ofturpentine, oil of lavender, or benzine may accomplish the same resultas sulphuric ether, chloroform, gasoline, petroleum ether, bisulphuretof carbon, and othersimilar volatile substances may be taken instead ofsulphuric ether, either single or in mixtures with each other.

A good working composition I consider to be consisting of the followingingredients, viz: Eight parts oil-colors; one part oil of turpentine;four-eighth parts sulphuric ether, all the parts taken by weight. Theseingredients so composed and thoroughly mixed, when used by means of anatomizer or air-brush, will form a coloring-liquid allowingto be easily,accurately, and rapidly distributed upon drawings or paintings.

' I do not limit myself exactly to the proportions as above given.

What I claim, and desire to secure by Letters Patent, is

to be used for finishing photographs or any other'pictures by means ofan atomizer or air-brush, said composition consisting of oilcolor, (oroil-paint,) oil of turpentine, and sulphuric ether, in or about theproportions as stated. 7
